We update the spectrum of Nova Oph 2010 obtained on Feb. 12. The profiles of emission lines don't almost seem to largely change. We continue the observations of this object.

We update the photometric and spectroscopic results of the recurrent nova U Sco. The recent spectrum shows that the emission lines of the Balmer series become weak comparing to those of previous phase. The photometry indicate that the this nova evolved in the plateau phase.
